You are conducting a test of homogeneity for the claim that two different populations have the same proportions of the following two characteristics. Here is the sample data. Population Population Category A B Category The expected observations for this table would be Population Population A B Category A #1 16 34 B The resulting Pearson residuals are: Population Population #1 = #2 73 123 #1 I #2 #2 What is the chi-square test-statistic for this data? x² Report all answers accurate to three decimal places.

Please answer the question in the photo. Thank you!

Listed below are amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Assume that the  distributions for each state are normal and that all variances are equal.   Arkansas       4.8    4.9   5.0     5.4   5.4    5.4    5.6    5.6   5.6   5.9   6.0    6.1 California.     1.5     3.7    4.0    4.5   4.9    5.1     5.3    5.4   5.4   5.5   5.6    5.6 Texas.           5.6     5.8    6.6    6.9.  6.9    6.9    7.1     7.3    7.5    7.6   7.7     7.7
